In the span of a few days, I experienced a system crash on both my PS4's; same scenario, same error code: CE-34878-0.

The crash always occurs after the same exacts steps:

-wake-up console

-log-in into my profile

-start World of Tanks

black screen - no more interaction possible from the controller;

Manual shut-down from the power on/off button;

restart, and PS4 goes into recovery mode and self cleaning;

I contacted Sony after I made certain WoT code was not the culprit;

If you ever get a black screen and error code CE-34878-0, it means you have some corrupted data in the lines of code somewhere. We did an extensive set of tests, and it turns out that Sony recommends a minimum of 5 Mbps of upload speed for an "healthy" connection to the servers.

My nominal upload speed is 3 Mbps, as per the plan I have subscribed to, but during peak hours, I noticed that I have less than 1 Mbps.

According to Sony, less than 1 Mbps would be a contributing factor to packet losses, resulting in data corruption.

What is the solution?

Recommendation is to reset your console, and download the games again.

Here you are guys, my 6 cents...I have 20Mbps upload and it happens once a week.

End of passion play, crumbling away I'm your source of self destruction. Veins that pump with fear,sucking darkest clear leading on your death's destruction. Taste me you will see more as you need dedicated to how im killing you.
